Trezor Safe 7 Review: The Only Trezor That Works With an iPhone
How we reviewed this: from the manufacturer’s own documentation and published security research.
Trezor’s flagship is the first with Bluetooth, an openly auditable secure element (the tamper-resistant chip that guards your keys), and post-quantum cryptography. It is also the only Trezor with a publicly disclosed flaw in its secure element — found, as it happens, by Ledger, whose Donjon lab also found a separate microcontroller weakness in the Safe 3.

Buy it for one reason: it is the only Trezor an iPhone can actually sign transactions with. Every other Trezor gives iOS users portfolio tracking and receiving only — you still need a desktop or Android device to send.[3]
If you do not need that, the Safe 3 at CAD $89 protects your coins just as well for about a quarter of the money. This is a CAD $300 premium for a screen, a battery and Bluetooth.
The chip vulnerability, in proportion
In late January 2026, Ledger’s security lab, Ledger Donjon, found a flaw in the TROPIC01 chip inside the Safe 7. Tropic Square confirmed it. Laser fault injection can make the chip run custom firmware and expose certain secrets, and because it is a hardware issue, it cannot be fixed with a firmware update.[2]
- Physical possession of your device
- Disassembly, desoldering and backside decapsulation of the chip
- Specialised laboratory equipment and real expertise
Trezor’s position is that funds stay safe, and on the published facts that is fair. TROPIC01 is one of three security layers. The attack cannot defeat your PIN and cannot be used to build tampered devices for resale. An attacker would have to break the other two chips and brute-force the PIN as well.[2]
The part worth sitting with: this flaw is public precisely because the TROPIC01 is designed to be openly auditable. A competitor’s lab could examine it, and did. The closed secure elements in every rival device have not been through that, which is not the same as being clean. Judge the Safe 7 on the flaw if you like, but know that you are partly penalising it for being inspectable.
What the money actually buys
Against the Safe 3 at CAD $89, the Safe 7 at CAD $389 adds:
- Full iOS support over Bluetooth 5.0+, which can be switched off in settings. This is the only genuinely functional difference for most people.[3]
- A 2.5 inch colour touchscreen, 62% larger than the Safe 5 — materially easier for checking a contract or a long address.[1]
- A second secure element. The EAL6+ Optiga is still there; the TROPIC01 sits alongside it as an auditable third layer.
- A battery and Qi2 wireless charging, plus an aluminium unibody and Gorilla Glass 3.
- Post-quantum cryptography, which matters on a horizon nobody can date.
None of that makes your keys meaningfully safer than a Safe 3 today. It makes the device nicer to use, and it makes it usable from an iPhone.

Buy direct, not from a reseller
This applies to every hardware wallet and it is not a formality. In August 2026 a breach at Trezor’s fulfilment partner exposed shipping details for around 14,000 buyers.[4] Nothing on the devices was compromised, but it is a reminder that the supply chain is the soft part. Order from Trezor directly, set up the device yourself from a blank state, and treat any unexpected call or email about your order as hostile. Trezor will never ask for your recovery phrase.
Who should buy which
The only Trezor that can sign from iOS. That is the whole case.
Same EAL6+ protection for your keys, about a quarter of the price.
Colour screen, no disclosed chip flaw, CAD $190 less.
Bluetooth and full iOS, at EAL5+ with partial-open firmware and an SE low-level NDA.
The best hardware wallet Trezor makes, and not the one most Canadians should buy. At CAD $389 it is more than four times the price of a Safe 3 that keeps your keys just as safe, and the extra buys convenience rather than security.
The exception is real though: if you live on an iPhone, this is the only Trezor that will let you send from it. Weigh that against a Ledger Nano X at CAD $119, which does the same job on a lower-certified chip with partial-open firmware and an SE low-level NDA. That is the actual decision.
Trezor and Ledger prices are both the makers' own Canadian listings, read on 31 August 2026. Specifications were verified against Trezor on 25 August 2026 and can change without notice. We have not physically tested this device; this review is built from the manufacturer’s published specifications and disclosed security research. Nothing here is financial advice.
